Bid-Ask Spread

Sure, here is the definition of the three terms:

Bid-ask spread: The difference between the bid and ask prices for an asset. It is the spread between the highest price a buyer is willing to pay and the lowest price a seller is willing to accept.

• Bid: The highest price a buyer is willing to pay for an asset.
• Ask: The lowest price a seller is willing to accept for an asset.

The bid-ask spread is a measure of the market liquidity for an asset. An asset with a low bid-ask spread is said to have high liquidity, while an asset with a high bid-ask spread is said to have low liquidity.
